Designing high-power Class D audio power amplifiers | EE TimesHigh Power Audio Amplifier Schematic - A power amplifier circuit is the one with minimum output impedance, used to drive loads like a speaker, which require high power at low impedance.. Endih mengatakan Hello, For the Schema 20kW audio amplifier, you should discuss that schematic with its designer (Mr Glen Klienschmidt). According to Mr Glen, he was designed this power amplifier for experimental purpose only.. The circuit has been designed to produce an audio amplifier that can be used for low efficiency speakers or outdoor sound systems since it can deliver 300W of power. Power Amplifier – a type of amplifier built and designed for the purpose of delivering and supplying sufficient and maximum high.
